KWA RM4 SR10 AEG Airsoft Rifle w/ 2GX 9mm Gearbox - BLACK

KWA has always been manufacturing the industry's most prevalent AEGs engineered to function smoothly and reliably right out of the box. The KM4 SR10 Generation 3 model takes that level a step further. This full-sized AEG rifle features the all new 2.5 system and their kinetic feedback for a realistic recoil punch in every trigger pull. Externally, its rugged full metal construction (full metal receiver, barrel, internals), a high-quality enhanced gearbox and ultra high-torque motor set up, and a Mil-Spec-1913 full metal free floating rail system, lets you run mounted accessories like a tactical stubby vertical foregrip.

KWA's KM4 SR10 is equipped with 9mm steel ball bearing bushings and a quick spring change system. This airsoft gun also has installed a lengthy, robust free-floating MIL-SPEC-1913 Picatinny RAS (Rail Adapter System). This laser-engraved RAS allows for quick upgrade potential, giving you freedom to customize your weapon with add-ons such as lasers, tactical flashlights, with enough length to even be outfitted with a grenade launcher unit. A clear top sight rail gives you freedom to mount pretty much any optic out on the market.

The SR10 is a full-size airsoft rifle, and the extra barrel length over the more compact SR5 and SR7 variants allow for the SR10 to be more powerful and accurate. Because a 5-point retractable rear stock is installed, the SR10 does not sacrifice quick maneuverability. In addition, KWA has perfected an AEG to similarly replicate the AR-15 model. The comparison allows limitless customization to cater with the airsoft user's interest. So customize away and feel the realistic kickback from one of KWA's finest!

Ammo type:Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs. For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Color: BLACK

Battery Charger Recommendation: Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.
